IE 11 is the last version of the Internet Explorer web browser by Microsoft.
It was officially released on 17 October 2013 for Windows 8.1 and on 7 November 2013 for Windows 7. The browser was also shipped with Windows 10 on its release on 29 July 2015, but Microsoft Edge is the default browser in this version of Windows.
After 12 January 2016 only the most recent version of Internet Explorer to be offered for installation on any given Windows operating system will continue to be supported with security updates, lasting until the end of the support lifecycle for that Windows operating system. On Windows 7, 8.1, and 10, only Internet Explorer 11 will receive security updates for the remainder of those Windows versions' support lifecycles.
